Just to make it clear to everyone:
Samsung D880 Duos is a 2-Sim card (GSM+GSM) Standby mobile phone. What it means is that it can receive calls from 2 operators simultaneously without any prior adjustment in the phone applications. Hope it helps to resolve your doubts^^

you have shown with a dual sim features phone.that samsung also can bring dual sim phone on the market for compeition on the market with another brand.....................they should bring the phone early coz china has bring the phone with a good pricing of the phone........

Well done Samsung. With a huge segment of people waiting for a branded mobile with 2 Sim Cards i am sure that you will give the other competitors a ride for their money. Thought the markets are loaded with similar devices form China unfortunanetly they are not branded products. This is for a sure hit.
